The Schedule referred to in these Letters Patent and making part of the same www I, SAMUEL B, SEXTON, of the city of Baltimore, in the State of .Maryland, have invented certain new and useful Improvements in Fire-place Stoves and -Flne-Casings therefor, of which the following is a specification.

Secondly, in surrounding the upper part of the fuelmagazine with an air-space or chamber, communicating freely with the air-heating space between the stove and its rear casing, and masked in front by a screen of any suitable construction, Awhich may or may not constitute a permanent part of the walls or shell-of the stove, and is adapted to permit the passage of air.

Thirdly, iu a due-casing, ,which may remain permanently sctiu the {ire-place, while permitting the introduction and removal of the stove.

General Description.

A A are the the walls of thel main combustionchamber.

B is the fire-brick lining, the inner surface of which is formed with vertical `ribs or corrngations, as shown' in figs. 3 and 6.

The grate C may be constructed with a risc, c, in front, to retain the burning fuel.

D D represent either hinged or sliding doors, with apertures al' above and below the grate.

The upper range d of these apertures` may be closed with mica or other material for illumination, while the lower ones, d', are left open to admit air; but these may,;.of .conrse, be provided with valves or registers to check combustion.

The upper part of the magazine or fuel-reservoir E is surrounded by an fair-space, F, communicating freely with the heating-'space behind the stove, and.

screened in front by a wall or casing, G, which may be perforated or formed with any. suitable open work to permit a free circulation of air around'andv in con-l tact with thewalls of the magazine.

'The lower part, E', of the magazine may be cast in one piece -with the crown A of the main combustionchamber, or may be separate therefrom, and either' connected or not with the upper partof the magazine.

action of the fire and changes of temperature," and at the same time to adapt it to deliver the fuel more freely, -and lessen the danger of clogging.

Communicating with 'the interior of the .crown 'ori upper part of the combustion-chamber are tubes H H H, which also connect with an upper chamber, 1',

from whence a horizontal flue, J, leads to the interiorv of the hollow casing K K', which forms. au extended" chamber, L, for radiation; y

Within this radiation-chamber are partitions k k1 lo k, to' conduct the gaseous products of combustion in a circuitous course, and distribute them throughout the chamber.

In the -partition k3 is adamper, M, guarding an aperture, to aord direct' draught when desired.

.The damper M may be made to slide, -as shown in iig. 3, or it may be hung on either vertical or horizontal hinges, the operating yrod fm, being attached directly to-it, as illustrated in iig'. 7.

N is the discharge iiue.

O represents an aperture in the casing, through ,which the workman putting 11p the stove may have 'access to the flue-pipe N to adj ust it on its collar.

1?' P represent a range of apertures, through which external air to be heatedrmay be admitted through the casing underneath the radiating sheet ue or chamber L, to the space between the stove and casmg.

. R is the register or valve, operated by aroma, to

The said'lower part E is formed with vertical ribs.-

permit the escape of gas from the magazine into the discharge-dues.

S is a chute, through which the magazine may be supplied with fuel. The said chute may be closed by a hinged or sliding door, s, in any common way.

The flue J may be provided with a checkltlue, j, but this is not generally necessary, except with chimneys of very strong draught.

' Operation..

XVhen the fire is tirst made, the valves or dampers R andM may both be opened, to afford the most di rect communication with the discharge-flue N. Both these valves are afterward closed, audthe doors D may be opened or not, as preferred. The magazine being filled with fuel, active combustion will be maintained `around its lower part in customary manner.

The gaseous products of combustion, passing npward through the tubes H, fill the chamber I, and are conducted by the horizontal flue J into the radiating sheet-due L, within which they are deflected and distributed by the partitions k l: k1 k2, as indicated by the arrows 1 in g. 7, and finally delivered to the discharge-flue N.

The arrows 1 indicate the course of the gases-when the damper M is closed. This damper, is however, represented open in g.'7, in order to show the aperture which it is intended to guard. l

The arrows marked 2 show the ingress of external air to be heated.

The permanent tine-casing KK may be used with stoves of various kinds.

. One great advantage of this pal-tof my invention consists in the facility afforded for setting -the 'fluecasing without incumbrance from the Stove, and subsequently introducing and removing a stove as often as necessary, without disturbing the fine-casing or the smoke and hot-air dues within the chii'nney.

In fire-place heaters, as usually constructed, it is diicult toget att-he Hue-pipe to set in place, and great inconvenience is experienced from the frequent necessity of taking' out the stove for cleaning and other purposes, the pipes having to be detached and disturbed'on every occasion, and in many cases the registers removed to rcadjust them.

With my invention, the openingl is made in the wall to admit fresh air from the outside, and the radiator or casing K K', without the stove, is then set in position in the fire-place, and the smoke and hotair pipes are attached.

The workman is enabled. to perform this duty with great ease by reason of his having the entire space to work in, which is afterward to be occupied by the stove. The casing having been set in its place, any suitable stove is introduced, the fine-pipe F being inserted in a collar or opening, J', prepared for its reception in the casing K.

Either a common close 'st-ove or an open-grate stove may be used in this way with advantage.'

`When the stove is removed, the front of the casing or radiatorlmay be closed by a screen or shield, such as is described in my patent dated December 14, 1869, so as to make a neat finish in connection with the sides or front of the flue-back or radiator.

An important advantage of the particular form of stove which I have shown consists in exposing the central part of the magazinel to a free circulation of air, while at the same time it isconcealed from View.

The feed-chute S also passes through this air-space instead of through a gas-space, as is usual.

By carrying the gases from the main combustionchamber1 through several tubes H, I provide a 'greater radiating surface, and at the same time make the due-tubes more durable than when ,they are surrounded by Iire and heat without air. The air-charnber through which these tubes pass, may be inclosed in wholeI or in part by an open-work case or cover, censtituting a screen, while permitting the passage o air.
